MARSTEK CT003 Smart Meter 1 /3Phase

The Marstek CT003 is a compact and versatile smart meter designed to collect real-time energy data and connect it to energy storage systems. With support for P1 and infrared communication and Wi-Fi and Bluetooth connectivity, it's ideal for integration into modern home energy systems.

Features & Benefits

• Communication via P1 & IR — The CT003 can communicate directly with the energy meter via P1 interface or via infrared (IR).

• Real-time monitoring & automatic energy distribution — the device continuously reads consumption and adjusts the power supply from the battery (or other sources) to minimize injection (feed-in) to the grid (“zero injection”) and thus optimize costs and consumption.

• Connectivity — Supports Wi-Fi (802.11 b/g/n) and Bluetooth 5.2 for communication with apps and power management systems.

• Powered via USB-C (5V) — the device is powered via a USB-C connection, making external power easy to manage.

• Compact size and lightweight — relatively small and light, making installation easy.

• Low self-consumption — the device consumes less than 2 W in operation.

• Robust temperature operation — works reliably in a temperature range of approximately –20 °C to +45 °C.

• Marstek System Compatibility — Designed to integrate with the Marstek VENUS, JUPITER, SATURN series, and other energy management products.

• Warranty & Reliability — Marstek offers a 10-year warranty on this product.

• Optimizing self-consumption — by intelligently controlling when solar energy is stored or returned, consumption and costs can be optimized.

• Energy management & balancing between sources — the device can help use surpluses from one source (e.g. solar energy) to reduce grid usage.

• Integration within a smart energy system — as part of a system with home batteries, inverters, and energy management software.

• Monitoring & reporting — use the accompanying app for insight into power usage, history, and trend analysis.
